River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ...

Abstract Energy costs not included in consumer utility invoices include human health problems triggered by air pollution from burning fossil fuels, and environmental degradation caused by global warming, acid rain, and water pollution. Such costs, peripheral to energy pricing, are called externalities because electricity producers and users do not pay for them directly. Society as a whole must pay. This pricing system masks the true costs of fossil-based electricity generation plants, result...

Although considered a rare disease, endemic to low-income regions and unsanitary environments, leptospirosis is still encountered in some parts of Romania, in both rural and urban environments. Its specific pathways of transmission caused it to be a threat to people working with animals, pest control, farmers or those whose jobs place them in the presence of waters, sewers or in flooded areas. This paper investigates the occurrence and effects of leptospirosis by analyzing 17 cases of infec...

The performance of cathode affects the overall performance of a microbial fuel cell (MFC), and cathode configuration affects the fabrication cost of this bioelectrochemical system in a large way. Various modifications in cathode structures have been observed in MFCs. Among them air-cathode MFCs are considered to be the most efficient and sustainable option due to elimination of aeration, as required in aqueous cathodes which consumes energy and increases operating cost of MFCs. An air cathode us...

Influence of soil pH on the mechanical characteristics of glass reinforced plastic (GRP) pipes type was often investigated in different situations encountered in the field. GRP degradation is directly proportional to the exposure to soil with non-neutral reaction. The theoretical and experimental results lead during time to design standards, which allow the application of GRP pipes in water and soil, so as minimum interferences with the materials used in the manufacture of pipes would appear. Sa...

Bare zero-valent iron nanoparticles (bare-ZVIN) have a great tendency to aggregate, which drops their reactivity with pollutants. To address this issue, polyvinylpyrrolidone stabilized-ZVIN (PVP-ZVIN) was synthesized and used for the removal of Cd2+ from aqueous solution in a batch system. The effects of operation conditions such as the pH of aqueous solution (2-8), reaction time (0-120), adsorbent concentration (1-6 g L-1) and the initial Cd2+ concentration (10-60 mg L-1) on the removal efficie...

Petroleum hydrocarbons not only are toxic to humans and other living organisms, but will also pollute groundwater. It is thus critical to decrease the concentration of these pollutants in soil. Phytoremediation is an effective way to remove toxic compounds from soil. The current study used sorghum (Sorghum bicolor (L.) Moench) and barley (Hordeum vulgare) to reduce petroleum hydrocarbon content of contaminated soil around Isfahan Oil Refinery (Isfahan, Iran) and assessed the concentrations of pe...

The ecological risk related to the wastes disposal is that attached to functioning, closure and the post-closure phases of an ecological landfill lyfe cycle. The prediction of ecological risk in each of those three phases - i.e. the manifestation and evolution of possible negative consequences of different severities for different environmental targets - is an endeavor that organizations that possess and operate those ecological landfills should consider in order to ensure the maximum protection...

As it is widely known, according with European directives, the correct approach for waste management is based on a strict hierarchy of prevention, reuse and recycling, energy recovery and final disposal. In that way, all the countries have to strongly move in urban waste reduction and recycling promotion. The principles of the Circular Economy have become part of the European and other extra Europe Countries regulations. The European pack on Circular Economy suggests ambitious objectives by 203...
